This fairing has an opening immediately adjacent the housing 42. The peripheral portion of the fairin defining the opening is offset to receive a cover connection with certain specific embodiments,

the principles involved are susceptible of numerous other applications that will readily occur to persons skilled in the art. The invention is, therefore, to be limited only as indicated by the scope of the appended claims. j

Having thus described the various features of the invention, what I claim as new and desire to secure by Letters Patent is:

1. A wheel comprising a casting including a hub having a radial flange supporting a drum provided with a flange, the outer periphery of said flange having stepped cylindrical surfaces forming a shoulder, a rim having an edge deformed to embrace the stepped contour of the flange, and a tire retaining ring having an interwhen subjected to the axial force of a'tire thrust 5' against said ring.

2. A wheel comprising a casting including a hub having at one end a radial flange supporting a drum provided with a flange having a shouldered periphery; a radial disc carried by said 10 hub at the other end having an offset portion and a peripheral flange, a cylindrical rim having one edge deformed outwardly and embracing said shouldered periphery and the other edge being turned to embrace said peripheral flange l5 and having an annular portion provided with a circumferential slot, adapted to seat on the disc offset portion adjacent said latter edge, and a pair of tire retaining rings slidable on said cylindrical rim, one of which is adapted to seat go against the rim immediately adjacent said shouldered periphery, and the other of which is adapted to engage a split ring lock seated in said annular circumferential slot.
